v to has an overhanging cover which closes theV r tion of later;

in accordance with the average thickness of the lifts being presented.

In utilizing the machine for the applicay to Wedge lifts, it is necessary to present/thesey lifts to the applying rolls rolls will bear evenly upon the whole width of the lift.

Accordingly, one end face vof the illus-vr trated chute is made adjustable to vary the leno'th of the chute, to equal the'wi'dth 'ofthe weugelifts so. that they must Vbepresented axially and the adjustable face just referred spa'cecbetween'said face and the adjacent end ofthe Ychute opening, thus excludingrdirtxat this point. Further to'facilitat'e this oper tion y.ofl coating wedgeilifts, yone of the illustratedapplying rolls is yieldingly mounted, being spring-pressed: toward; the other V roll andlimited in `its inward movementyr faces ofshoe parts, such as heel lifts, it is found. desirable to provide a yielding surface upon each of the applying` rolls. 'In addition to this and because of the variation inthe thickness of diferentvse'ts of lifts, provision is also made, in accordance with another fea# ture of the invention-, for mounting one of the illustrated applying rollsA for adjustment toward the other-roll.;V j

ln order that thequanti of latex applied to the work may be controlled'readily without coagulation, the illustrated machine .is

provided with doctor or scraper rolls whichr are turned in the same direction'lof rotation as the applying rolls but with a much smaller peripheral'speed, and provisionis made forA edges of a latenV receptacleibelowthe applying rolls for preventing thenpieces of work from adhering to said rollsand in a construe; tion `by means of which latex picked up by said strippers may be carried back into Vthe late' eceptacle. Y

till `another feature of the invention `resides in theprovision ofA an inclined workguiding or diverting member beneath .the delivery opening of the machine. This mem.-

ber is arranged to guice the worlrvvith as little disturbance of its coating as possible verting thembeyond the bounds of the receiving device. Y.

These andotherv features of the invention will now be described with reference to the accompanyingV drawings in which: y A

vFig. 21is a rhorizontal section with parts broken away; Y Y Y Fig.3 is a fragmentary perspectiveof a vrFighe is a detail section of thei diverting ing the work strippers.

The illustrated machine embodies a pair of rotary applying rolls 10 and 12 j ournaled side by side upon substantially parallel, horizontal Y axes within a supporting casing 14,- the `roll 12 beingsupported upon a shaftV 16 directly -journaled in bosses 18 formed upon the sides of the casing. Each of the rolls may be made Vupof a hollow @cylindrical metallic roll 2O H provided with a yielding applying surface 22 BecauseY of 'the irregularities in the suny which preferably is somewhat yielding in or- 'derfthat the surfaces .of the rollsmay conformito slight irregularities or wrinkles in thesurfaces of the pieces of work. The surface 22 may be madeof a gelatinous compound, similar to that used on the ink rolls of printing presses, which is unaffected by the the casing 14. This hanger 26'With the roll 10 is resiliently urged toward the other roll 12 by means ofa spring 32 surrounding a rod 34 which is pivotally attached at one end to said hanger and at its other rend passes through a boss 36 "in the casing through which its movement vis limited by means of an adjustable stop nut`38. This nut is disposed in a convenient position upon the outside of, the casing 14.y

The supply of coating material, such as latex, is carried in receptacles 40 and 42 shown as formed integrallywith the casing 14 and having separate inclined edges 44 and 4 6 which are separated to provide a delivery opening 48 through which treated pieces of work may drop. To facilitate the maintenance of a proper quantity of liquid in these receptacles, a barometric supply device is provided comprising hollow brackets 50 secured by thumb screws `51 tothe casing 14 to com- 'municate with the receptacles andarranged 40. `tityof latexis unattended by any detrimental www j to support in inverted ,position supply bottles S2-Which rest upon :rubber Washers 54vv and :are

Devices of one sort or another called cvdoctors are "commonly employed in cementing f machines for regulating: thequantity ofmaf terial upon vthe surfaces oftheapplyingrolls.-l In using vlatex in J such machines, it-'has been found that a doctor in .the forni` of Va scraper bar is ill adapted because anyfrictional-action between the' scraper andthe' lateXsets up .a co-v agulation which; forms balldike iiias'sesof rubber Which bear against the vsurface `of the applying'roll andremove material therefrom in* streaks... yOn theother hand, a 'rotary doctenor-scraper roll turning in theoppositedi v Arection of rotationfrom the applyingrolhso that adj acentsurfaces are' moving inthe saine q lly iny that direction): causes .asqueezing ofthe liovveve1l,:that ifltliejrota'ry doctor roll is posiV torrrollwmay be determined by controlling` j. latexbetweenthe tworolls andV sets fup coagu. 35'.'

Y Tliejsorting table l2() v ticul-atedsides'128 and bottom l29carriedl vupon-a framework V which is supported by incansof brackets 132 (Fig. v 1).-*bo'ltedfto the` .casing 14 ofthe machine. This allows the lijf-ts -to begspread out inconvenient position s out so that( v is providedivith re# 24k for the operator and at the same time permits dust and dirt which may have collected with the lifts to pass-through the reticulated bottom 129 ofthe sorting table. This sorting table is joined adjacentv to its centralportion to a cover member 136 (Fig) provided with an upstanding vrim 1138 surrounding an inlet opening communicating with the guide chute 1122, a part of which is formed as apart of the lone of these side members is secured to a. rod

146 extending through and pivoted in the,

outer sides of the casing 14. v'lhep'osition of this pivoted side 144, which is located between theend members 140, may be determined by means of an-arm 148 connected toY a rod 150 passing through a boss A152 upon the casing. An adjustable stop screw 154 limits the upward movement of the rod 150 n under the. action of a spring 155 surrounding sa-ld rod, said spring'belng suiiiciently stiff normally to prevent mo-re than a single lift from passing through the outlet of the. guide chute and sufficiently resilientto permit the side ,144 tofbe pushed aside slightly in case a lift,'such as a wedgelift, having a partV thicker thanthe width of the outlet opening has passed partly therethrough and been seized by the applying rolls, thus preventing l breakage of the machine.

In handling lifts of substantially uniform thickness, it is not material whether I the rounded end or the'heel-breastV end of the lift is passed first through the rolls, or, indeed.

' l whether these lifts are passed through sidewise or endwise. On the other hand, because a transverse cross-section in any direction is substantially rectangular, when the operator is dealing with wedge lifts where a crosssection from front to back, or in any direction except at right angles to its longitudinal axis,

is inherently tapered, it is important thatV vthey be passed through the rolls with either the thinnest or the thickest edge foremost so that the cross-section of the part with which the cement applying rolls are contacting at any one time is substantially rectangular; This insures a firm contact and an even coating of latex. This operation is facilitated by the provision in the guide chute ofan adjustable end piece 156 of a triangular shape, the position Vof which between the inclined sides 142 and 144 may be determined by a. screw 158 extending through the casing 14 and operated by a knurled finger piece 160 secured to the outer end of the screw. Associated with thisA triangular piece 156 is an eX- tension 162,;of thin? metal, the upper .end 164 of which is lbent over horizontall to cover part of the inlet opening defined y the upstanding vkrim 138,1thus excluding the dirt from the unused portion of the inlety opening -Whlea largepart of the Pieces of Work.

dropfreely away from the applying rolls through the outlet 48, it sometimes happens thatpieces .willfstick to one or theother of the Vapplying rollsv andl attempt to follow around into `the receptacles. To prevent Asuchaction7 strippers 170 are vprovided each comprising a'plate upon theupper surface of whichr are provided ribsv or fingers '172 '(Figs. land 5) having sharpened ends 174- vhich are. brought into close relation to the applying rolls'torake off anypieces of Work which Vmay be kclinging to said rolls. These stripper plates 170 are supported in inclined.

sof

positien above the'inclinededges 44 and 46' of the receptacles? by means of suitably formed lugslj176 wherebyV the' stripper plates maybe 'slipped over VVthe edges of said receptacles or removed therefrom for cleaning.

Adjustment of the position .of the roll 10 away'from the correspondingstripper plate 170 does not'destroy the effectiveness of the latter because the machine is then used for thicker lifts which cannot pass between the roll and the stripper.' It should be noted that the inclined plates 170 of the work strippers are so supported with respect tothe edges 44er 46 of the receptacles that any rippings Vpassing over either the upper or lowersurface of said plates (see Fig. 1) will be carried back into vthe receptacles instead of beingallowed to pass out through the opening 48. Y

ln spite of this provision, there are occasional drippings from theco-acting surfaces of the applying rolls and sometimes the pieces of work have an excess of coating material-which promptly drops oflI on the diverting trough 124.v For this reason, said diverting member is made of corrugated materialf having Vribs 180 and. intermediate grooves 182. When a heel lift, such as that shown at 184, slides over the surface of the diverting member, itrests upon the ribs 180. Since any drippings which may have been deposited upon said member are carried into the grooves 182, the removal of an excess of lat A material frolinthelifts 1.84.7is' preventedand may have collected on the diverting member; x Incase the quantity of drippings vis suiiicient; so Vthat it runsdown'the'grooves 1825 a gutterA` agulated ffdrippings :0r possible dirt :which 186'is provided atthe bottoni of saidldivert'- i ing memberV 124iV extending.

When -it yis desired 'to 'empty 'either ofthe c receptacles 40 or 42, a pan maybe placed upona corresponding shelf 190' or 192 yupon the legs 90'and 92as the'bracket migr?
